This webinar outlines the concept, design and execution of appropriate validation strategies and procedures intended to mitigate microbiological hazards in Low-Water Activity Foods. In the context of FDA regulations, low-water activity foods (LWAF) are those products with a water activity (aw) of less than 0.85. For many decades, these products were believed to present a low microbiological hazard risk. Various food related illness outbreaks, starting with a massive outbreak of salmonellosis due to peanut butter consumption in 2008-2009, raised awareness of the risk resulting from extended survival of pathogens in these products even in the absence of active growth.

High-Pressure Processing is a food processing technology that enables food safety while maintaining food quality. Learn how this high-pressure technology contributes to food science and testing to help support HPP processing and HPP food safety.

Validation of aseptic fillers intended for the production of low-acid, shelf-stable products is a core requirement of the FDA’s low-acid canned food (LACF) regulations (21CFR113 and 108.35). Microbiological challenges of the aseptic zone and packaging material sterilization cycles are important components of the validation process. These challenges are often conducted at the production site using non-pathogenic surrogate organisms that mimic the resistance of the pertinent target pathogen. This presentation will provide a brief history of the use of such surrogates for the validation of low-acid aseptic fillers along with the approach we have used to qualify the surrogates as adequate for the intended technology.”
